The object of my invention is to produce a smoking pipe, of simple,relatively inexpensive construction which will retain within itself,such moisture as is generated as a result of the burning of the tobacco,and as is injected thereinto assaliva by the smoken'in such manner as topractically prevent nicotine-contaminated liquid from passing into themouth of the smoker.

The accompanying drawing is a slightly magnified section longitudinallyof the stem, and illustrates embodiments of my invention:

Fig. 1 is a section of a straight stem pipe; and

Fig. 2 a section of a drop stem pipe.

In the drawing I0 and II indicate, respectively,

the bowl and integral stem of a pipe. The outer end of the stem iscounterbored at I2 to receive the ensmalled end I3 of supplemental stem,or bit I4. Stem II is bored, at I5, from the bottom of the counterboreinto the bowl and within this bore I5 is mounted, convenientlypermanently, a tightly fitting metal tube I6 the outer end of which isspaced from the inner end of end I3 of stem I4, and the inner end ofwhich preferably extends to the axis of the bowl.

Immediately below bore I5, stem II is bored at I1, to form a cul-de-sac,or closed-end pocket, for the removable reception of the closed innerend of metal tube I8 which is mounted in bore I9 which extends axiallythrough stem I3-I4,

the outer end of tube I8 preferably extending close to the mouth end ofbore I9. The inner end of bore I9 is enlarged at I9 over the top of tubeI8 and registering with this counterbore is a perforation 20 through theupper part I of tube I8 into the interior thereof, thus dividing tube I8into a blind pocket or reservoir end R and a smoke -outlet end C.

The position of perforation 20 depends somewhat upon the distancebetween the bowl and the mouth end of stem I4, but in any event Vitshould be spaced from the outer end of tube I6 (or bore I5)- so that anysaliva entering tube I8 in quantities suflicient at any one time to llthe diameter of the bore of said tube, and thus having a tendency toflow outwardly through the perforation 20, may sink into the `inner endof the counterbore I2. In use, moisture rarely gathers in thiscounterbore. should be far enough away from the outer end of tube I8 toinsure condensation of moisture from the smoke at an effective distancefrom the mouth so as to permit the condensate to flow back intoIreservoir R rather than to be sucked into the users mouth, having inmind the fact that the farther away perforation 20 is from the sealedin- Perforation 20 ner end of tube I8, the greater will be the capacityof reservoir R. I believe that, in a pipe of the rrelative portionsshown in the drawing, perforation 20 may be effectively placed aboutmidway between the bowl and the mouth end of stem I3--I4. The bore oftube I8 should be large enough to receive an ordinary pipe-cleaner swab.

In use, the smoke is drawn from the outer end of tube I6, enters tube I8through perforation 20 and passes into the mouth of the user. Conden- 10sation from the Smoke occurs adjacent perforation 20, mostly within tubeI8 and flows into the blind-end reservoir end R of said tube. Salivaentering tube I8 will trickle into said reservoir end R. and, because ofthe gap between perfora- 15 tion 20 and the outer end of tube I6, willnot pass through 20 so as to produce frying in the bowl.

As a rather profuse wet smoker, I have found, in an extended use of apipe constructed as de- 20 scribed above, that a perfectly dry, coolsmoke is afforded and that no nicotine-contaminated liquid enters themouth.

After use tube I8 may be readily freed of liquid either by a snappyshaking of the pipe with 25 stem inverted, in a manner well known tosmokers, or by swabbing with a cleaner, either with or withoutseparation of stem I3-I4 from the bowl, and tube I6 may be readilyswabbed upon removal of stem I3--I4, tube I8 lying loosely in 30 bore I1and coming out with stem I3-I4.

Any slug of liquid in reservoir R cannot be sucked from the reservoirbecause of the intermediate perforation 20 and the closed inner end oftube I8. 35

I claim as my invention:

1. A smoking pipe comprising a bowl and separable bored stem, a metaltube mounted in the bore of the stem and having a closed inner end and aperforation through its top side intermediate its open end and its innerclosed end with a substantial length of said closed end lying within ablind pocket formed in the main body of the pipe, a comparatively shortnicotine pocket surrounding said tube between the bowl and saidperforation, the upper region of said nicotine pocket communicatingrespectively with the bowl and the said perforation.

2. A smoking pipe comprising a bowl and bored v stem, a metal tubemounted in the bore of the stem having a closed inner end and aperforation through its top side intermediate its outer open end and itsinner closed end, a substantial length of said closed end lying within ablind pocket formed in the main body of the pipe, a

Cil

comparatively short nicotine pocket surrounding said tube within themain body of the pipe at a point intermediate its closed end and saidperioration, a smoke conduit leading from the bowl 'to the bowl end ofthe upper region of said pocket,

and a second smoke conduit leading from the upper region of the bit endof said pocket to Said perforation.

3. A smoking pipe comprising a bowl and bored stem, a metal tube mountedin the bore of the stem having a closed inner end and a perforation anda metal tube in said Erst-mentioned conduit. 10
